LAMP HOLDER FOR MINERS CAPS.

Application filed August 2.3, 1922. Serial No. 583,809.

for Miners Caps, of which the following is a specification. V

This invention relates to improvements in lamp holders for miners caps and has as one of its primary objects to provide a holder which will permit of quick attachment and detachment of the lamp and by the use of but one hand.

Another object of the invention is to provide a holder comprising cap and lamp attached members adapted to have wedging engagement to an extent to provide against accidental displacement of the lamp and yet permit of its ready intentional removal.

Another object of the invention is to so construct the socket member of the holder that the other member may be readily guided into the socket and without the necessity of any tedious relative positioning of the parts.

Another object of the invention is to provide a device for the purpose stated which will be simple in construction, not liable to disarrangement of its parts, and inexpensive to manufacture.

In the accompanying drawings:

Figure l is a side elevation of the holder embodying the invention applied to a cap and supporting a lamp;

Fig. 2 is a vertical transverse sectional view on the line 22 of Fig. 1;

Fig. 3 is a horizontal sectional view sub.

stantially on the line 33 of Fig. 2;

Fig. 4 is a perspective view of the wedge member of the holder.'

In the drawings the numeral 1 indicates in general an ordinary miners cap and 2 the usual lamp which is to be supported thereon. The numeral 3 indicates the lamp supporting plate which is usually provided upon a cap of this class, and this plate comprises portions 4, 5 and 6, the portion 5 being extended at an angle from the lower end of the portion 4 and riveted or otherwise secured to the visor of the cap and the portion 6 extending rearwardly from the upper end of the portion 4 and being secured to the top of the crown of the cap, the portion 4 extending substantially perpendicularly at the front of said crown. The member 4 is ordinarily provided upon miners caps but it will be understood that any similar supporting means might be employed in lieu thereof.

Upon the front of the portion 4 of the member 3 there are secured two companion socket members indicated each in general by the numeral 7 and each of these members comprises an attaching portion 8 which is straight throughout a portion of its length as indicated by the numeral 9 and laterally curved throughout the upper portion of its length as indicated by the numera'l 10. The relatively adj acent edge portions of the members 7 are turned outwardly or provided with flanges indicated by the numeral 11, and these flanges form an obtuse angle with the attaching portion 8 of the respective socket members and, when the said members are secured to the face of the portion 4 of the member 3, will be inclined toward each other, defining between them and in conjunction with the portion 4 of the said member 3, a socket which is indicated by the numeral 12. By reference to Fig. 2 of the drawings it will be observed that the lower portions of the members 7 are gradually converged toward each other in the direction of their lower extremities so that the socket 12 is gradually decreased in width or tapered in the direction of its lower end. In like manner, because of the angular disposition of the flanges 11, the socket is gradually restricted in the direction of its open front. By curving the upper portions of the members 7 outwardly in opposite directions, a flaring throat is provided at the entrance to the socket, and the purpose of this construction will presently be explained.

The other or wedge member of the holder is most clearly shown in Fig. 4 of the drawings and the same comprises a body which is indicated in general by the numeral 13 and which is provided with an attaching portion 14 adapted to be riveted or otherwise secured to the rear side of the body of the lamp 2. The body 13 is, generally speaking, of wedge-shape, having side face portions 15 which converge inwardly from the outer face of the body and which also converge in the direction of the lower end of the body so that the body is tapered in this direction as clearly shown in Fig. 4 of the drawings. The socket members 7 are more or less resilient and it will be evident that their flanges 11 may therefore yield to a slight degree.

The outer face of the body 13 of the wedge member is indicated by the numeral 16 and is plane and parallel to the attaching portion 14 and it will be evident that the said member may be engaged in the socket 12 by introducing its lower end portion into the throat of the said socket and sliding the wedge portion downwardly between the downwardly convergedportions of the said socket members. The curved upper portions of said'socket members forming the throat will serve effectually as a means for guiding the wedge member 13 into place in the socket, and as the member is forced downwardly its beveled faces 15 will bind against the opposing sides of the flanges 11 as best shown in Fig. 3 and finally the said member 13 will become wedged within the socket, the plane face 16 of the said member substantially abutting against the forward face of the portion l of the supporting plate 3. In this manner the lamp may be conveniently arranged and supported upon the cap and because of the frictional wedging engagement between the parts comprising the holder, there will be no likelihood of accidental displacement of the lamp. It will furthermore, be evident that engagement of the wedge member in the socket and its disengagement therefrom may be eflected by the use of but one hand and in a most convenient manner.

Having thus described the invention, what is claimed as new is:

1. In a lamp holder for miners caps, a back plate adapted to be secured upon a cap, spaced members secured to said plate and having forwardly converging flanges at their adjacent edges, the said flanges also converging downwardly, and a wedge member removably receivable in said socket member and haying its lateral faces converging rearwardly and downwardly to engagebe tween and be frictionally held by the flanges of the socket member.

2. In a lamp holder for miners caps, a back plate adapted to be secured upon a cap, spaced members secured to said plate and having forwardly converging flanges at their adjacent edges, the said flanges also converging in a downward direction, and a wedge member removably receivable in said socket member and having its lateral faces converging downwardly and rearwardly to engage between and be frictionally held by the flanges of the spaced members, the upper ends of the said members and the flanges thereon being curved laterally and upwardly from each other whereby to provide a guiding throat leading into the space between the downwardly converging portions of the flanges.

In testimony whereof I affix my signature.
